.Net 3.5環境下常用數組性能測試

　　這件事情似乎很無聊但是沒人做我來做下苦力吧

　　以下是一些簡單的測試單位以ms計算注意裡面用到循環的數量有些事W有些是W

　　這些記錄可以作為編程過程中的一些參考

　　測試平台

　　奔騰G 雙核CPU
    G內存
    vs 調試環境測試

　　  一ArrayList (WW)

Stopwatch timer = new Stopwatch();
timerStart();

SystemCollectionsArrayList al = new SystemCollectionsArrayList();

for (int i = ; i < ; i++)
{
alAdd(i);
}

timerStop();

ConsoleWrite(timerElapsedMillisecondsToString() + \t);

Stopwatch timer = new Stopwatch();
timerStart();

for (int i = ; i < ; i++)
{
alContains(i);
}

timerStop();

ConsoleWriteLine(timerElapsedMillisecondsToString());

　　

　　  二Hashtable (WW)

Stopwatch timer = new Stopwatch();
timerStart();

SystemCollectionsHashtable ht = new SystemCollectionsHashtable();

for (int i = ; i < ; i++)
{
htAdd(i i);
}

timerStop();

ConsoleWrite(timerElapsedMillisecondsToString() + \t);

Stopwatch timer = new Stopwatch();
timerStart();

for (int i = ; i < ; i++)
{
htContainsKey(i);
}

timerStop();

ConsoleWriteLine(timerElapsedMillisecondsToString());
}





把timer提高到萬(Hashtable (WW))

    
   

　　  三HashSet (WW)

Stopwatch timer = new Stopwatch();
timerStart();

SystemCollectionsGenericHashSet ht = new SystemCollectionsGenericHashSet();

for (int i = ; i < ; i++)
{
htAdd(i);
}

timerStop();

ConsoleWrite(timerElapsedMillisecondsToString() + \t);

Stopwatch timer = new Stopwatch();
timerStart();

for (int i = ; i < ; i++)
{
htContains(i);
}

timerStop();

ConsoleWriteLine(timerElapsedMillisecondsToString());

　　

　　  四List (WW)

Stopwatch timer = new Stopwatch();
timerStart();

SystemCollectionsGenericList ht = new SystemCollectionsGenericList();

for (int i = ; i < ; i++)
{
htAdd(i);
}

timerStop();

ConsoleWrite(timerElapsedMillisecondsToString() + \t);

Stopwatch timer = new Stopwatch();
timerStart();

for (int i = ; i < ; i++)
{
htContains(i);
}

timerStop();

ConsoleWriteLine(timerElapsedMillisecondsToString());

　　把List換成List
